Vision-Language Instruction Tuning: A Review and Analysis
This work addresses the need for better instruction tuning in multi-modal LLMs, providing insights and tools for researchers, but it is incremental as it builds on existing VLIT methods.
The paper systematically reviews and analyzes Vision-Language Instruction Tuning (VLIT) settings and datasets, proposing guiding principles for high-quality data construction that improve multi-modal LLM performance in experiments.
Instruction tuning is a crucial supervised training phase in Large Language Models (LLMs), aiming to enhance the LLM's ability to generalize instruction execution and adapt to user preferences. With the increasing integration of multi-modal data into LLMs, there is growing interest in Vision-Language Instruction Tuning (VLIT), which presents more complex characteristics compared to pure text instruction tuning. In this paper, we systematically review the latest VLIT settings and corresponding datasets in multi-modal LLMs and provide insights into the intrinsic motivations behind their design. For the first time, we offer a detailed multi-perspective categorization for existing VLIT datasets and identify the characteristics that high-quality VLIT data should possess. By incorporating these characteristics as guiding principles into the existing VLIT data construction process, we conduct extensive experiments and verify their positive impact on the performance of tuned multi-modal LLMs. Furthermore, we discuss the current challenges and future research directions of VLIT, providing insights for the continuous development of this field.
